But if a weird bug here. With one party I went into Dragon's Eye level 2 and went over left to kill a few elite lizardmen and one troll. Then something came up, so I quicksaved and closed the app. Later I loaded the save... and somehow all of the trolls and wraith spiders in the cavern to the far left became notified of my presence! It was a very hard fight to fend them off.
Later, with another party, I went to level 2 immediately after killing the Lizard King on level 1. I went right and killed the phase spider and the first two bombardier beetles. Then I went left and killed the elite lizardmen and one troll. By that point I was out of spells and healing, so I retreated to the snowy exterior and rested. I then quicksaved the game at the end of level 1.
Eventually I loaded that quicksave and entered level 2. Suddenly a bunch of trolls and sword spiders came at me en masse from the right! Basically all of the ones down near the spirally tunnel toward the level 3 exit. And then, as I was fighting them, all of the trolls and wraith spiders appeared to my left and attacked my flank! It was a massive pitched battle, I was saved only by the Black Knight and the berserkers from the Horn of Valhalla.
So, in short, there seems to be some kind of issue with loading savegames in the 2nd level of Dragon's Eye. It did make for a fun, if tense, surprise.
